超声波传感器原理图和信息

这是一本关于Intel 80C51 以及广大的51 系列单片机的书这本书介绍给读者一些 新的技术使你的8051 工程和开发过程变得简单-This one of Intel 80C51, and the majority of the 51 Series MCU book on this book to give readers some new technology allows you to the 8051 project and the development process becomes simple

经典的电子数码时钟程序，拥有最简单的外围（共阳数码管），且时间误差极小！-Classic digital clock procedures, have the most simple and the external (total yang digital tube), and the time a very small error!

是一个关于速度开环控制的空间矢量交流调速程序-a c programe for an open loop AC motor speed control. Method: space vector pulse width module

对另一单片机传送过来的编码电平进行译码。并在16002上显示出接受到的字符-Transfer over to another microcontroller to decode the coding level. And 16002 characters on the show receive

16*16点阵，可能显示汉字，同时可以放出音乐-16*16

用C8051F020读取红外遥控，采用扫描的方法-C8051F020 read with infrared remote control, using the method of scanning

51单片机系统中运用电脑上的大键盘！ Keyboard接线 PS/2--------51 1 DATA------P3.4 3 GND 4 VCC 5 CLK-------P3.3 接在51的外部中断，触发方式为低电平 AT89x51使用12M Modified by Shen Peng! Postgraduate of 2003, 7 Department Harbin Engineering University-51 microcomputer system on the use of the computer keyboard! Keyboard Connection PS/2--------51 a DATA------ P3.4 three GND 4 VCC five CLK------- P3.3 Then in the 51 external interrupt trigger mode for low-level AT89x51 use 12M Modified by Shen Peng! Postgraduate of 2003, seven Department Harbin Engineering University

利用单片机的定时器定时，令十字路口的红绿灯交替点亮和熄灭，实现主支路路口的交通信号灯控制（尽可能保持主线的畅通，即在通常情况下，保持主线的放行，只有在支线到达时，才放行支线），同时采用LCD显示倒计时时间及当前灯的状态-The use of MCU timer timing, so that the crossroads at the traffic lights turn out light and to achieve the main slip road junction traffic lights control (as far as possible the smooth flow of the main line, that is, under normal circumstances, to maintain the release of the main line, and only arrived at the branch only when the release branch), while using LCD display countdown time and the current state of light

用keil c语言介绍8051单片机开发一本书 很不容易才找到的啊！-language used Keil 8051 development on a book not easy to find the ah!
